APPARATUS FOR THE EVAPORATION OF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 235,618, dated December 21, 1880.

Application filed November 11, 1880.

To all whom it may concern 7 Be it known that I, OLIVER L. F. BROWNE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements, in Apparatus for theEvaporation of Liquids, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. i

This invention relates to apparatus employing artificial heatfor the evaporation of liquids and it consists, chiefly, in the combination, with the evaporating-vessel, of a removable cover provided with a flexible or jointed ventiduct, which communicates with a condenser surrounded by a chamber containing liquid to be heated or evaporated.

It also consists in the combination, with the aforesaid covers and ventiducts, of a blower arranged to force into the furnace of the apparatus the steam collected in said ventiducts. v It furthermore consists in the combination, with said vendiducts and condenser, of an air- 2 5 chamber surrounding the condenser, and communicating with thefurnace of the evaporating works by means of a blower, all as hereinafter more fully described.

In the accompanying drawings, Figure is 0 a longitudinal section of a saline-water-evaporating apparatus provided with my improvements; Fig. 2, a transverse section of same. Figs. 3 and-4 are detached transverse and longitudinal sections, respectively, of the con- 3 5 denser; and Figs. 5 and 6 are detail views of the cover and its ventiduct, illustrating modifications in the construction of same.

Similar letters of reference indicate corre sponding parts.

F represents the furnace or fire-arch of the evaporating apparatus, andV the evaporatin gvessel, suspended over said nae-arch in the usual manner. Over each of the said vessels V, I place a removable steam-tight cover, 0, 5 of sufficient height and suitable shape to collect the steam emitted from the liquid in pro cess of evaporation. To facilitate the fitting of the cover to the vessel V, I make the former of a diameter which allows it to easily enter the latter and becomepartly immersed in the (No model.)

liquid, so as to effectually exclude the air from I underneath. it.

D denotes a ventidnct, connected at one end with the cover O. and communicating at the opposite end with a main or trunk pipe, P. To facilitate the application and removal of the cover to and from the vessel V, the ventiduct D is made either jointed, 'as represented in Figs. 1 and 2 of the drawings, or flexible, as illustrated in Figs. 5 and 6. The cover is made detachable from the trunk-pipe]? bya suitable coupling, E, so as to admit of readily repairing or renewing the cover when needed. By means of a suitable valve, to, between the coupling E and trunk-pipe P, the ventiduct D can be closed while the cover is off the vessel V, or disconnected from the trunk-pipe.

B denotes a fan-blower, connected to one end of the trunk-pipe P, and having its discharge communicating With the furnace F, said blower exhausting the steam from the pipe P, and forcing it into the fire to promote combustion of the fuel, and of the gases emitted from the same. The opposite end of the trunkpipe P is connected with a condensing-chamber, G, which is surrounded by a casingformin g an air-tight space around the chamber G. Said surrounding space is divided by a transverse partition, 1), into a water-chamber, H, and ainchamber K. The water-chamber H receives the brine or saline water, by a suitable conduit, 0, from the tank or cistern T, which is usually employed for clarifying the. brine preparatory to being evaporated.

A conductor, I, extended from the chamber H to the evaporating-vessels V V, and provided at each of the said vessels with a spigot, conveys the brine from the chamber H to the vessels V, in which itis to be evaporated and reduced to salt.

The passage through the chamber H causes the brine to absorb the heat from the chamber G, and become partially heated preparatory to entering the evaporating-vessel.

The cooling of the chamber Gr condenses the steam of the brine in process of evaporation, and the vacuum thus created in the chamber G by the said condensation, in conjunction with the absorption of the heat by the brine, greatly promotes the evaporating process.

The trunk-pipe is provided with suitable valves 1;, by means of which the steam can be directed to either the blower B or the condenser G, or allowed to pass in both directions, as may be desired.

The air-chamber K communicates with the blower B by a pipe, 6, thus applying hotair to the fire in the furnace F.

L represents an exhaust-fan, connected with the condenser Gr by a suction-pipe, I, said fan being employed for removing any excess of condensed steam that may occur in the condenser.

The operation of my invention and its effects are as follows: The vessels V V being properly supplied with the liquid to be evaporated, and the requisite heat applied to said vessels, the suspended and counterpoised covers O are brought down and applied thereto. The ventiduct D being connected with the trunk-pipe P, and the valve to opened, allows the steam to escape into the said trunk-pipe. From thence it is drawn toward the condensing-chamber G by the vacuum produced in said chamber by the cooling influence of the brine circulating around it on its way to the evaporatingvessel V.

111 works where a great number of kettles are employed, or in case the condenser is unable to receive the steam as rapidly as it is generated in the vessels V, the valve 0; at the opposite end of the trunk-pipe is opened and the blower B set in motion. The latter draws the steam out of the trunk-pipe and the covers communicating therewith, and forces said steam into thefirein the furnace F. Simultaneously with the current of steam a current of hot air is drawn from the chamber K to the blower B and forced into the fire, thereby materially aiding the combustion of the fuel and its gases.

Whenever it becomes necessary to remove the cover from the vessel V, for the purpose of obtaining access to the brine in process of evaporation, the valve a in the ventiductD is closed and the cover raised the requisite height. A counterpoise, r, connected with the cover, facilitates the removal of same.

The fan L is employed only when an excess of condensed steam is present in the condenser Gr, said fan being designed'to exhaust said condenser.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination and arrangement, in an evaporating apparatus having one or more evaporatingvessels heated artificially, of a removable cover or covers for the respective vessels and a trunk-pipe, connected with said cover or covers by flexible or jointed steamducts and communicating with the furnace of the evaporating-works, substantially as set forth.

2. The combination, with an artificiallyheated evaporating -vessel, of a removable cover, a ventiduct connected with said cover. and a condenser communicating with said ventiduct and surrounded by a chamber intercepting the liquid on its way to the evaporating-vessel, substantially as shown and set forth.

The combination, in evaporating-works having one or more evaporating-vessels provided, respectively, with. removable covers, of a trunk-pipe connected with the said covers by flexible or jointed pipes, and having communications with the furnace and with a condenser, and a valve or valves separating said communications, substantially as set forth.
